Well, some closing thoughts on this thread. I never did reach full potential of the initial build. The Eagle heads that I used were used Ebag pieces. Had to replace four bent valves when I received them. The guides look fine when I replaced the valves. Obviously, I was wrong. The piece of guide that hangs down into the port snapped off on cylinder two. Two thirds of the guide stayed on the stem, the rest got smashed between head and piston. Smashed the **** out of the upper land. So, out that engine came and in went a 2012 Eagle with 6.4 cam and TTI headers that I had acquired for a score awhile ago. I did not lock the phaser, nor did I mess with any of the MDS. Installed the 08 tone ring on the crank and let 'er buck. **** it, just reused the fasteners. Roadkill style. It runs good enough, just not as fast as the other one. I messed with carb and timing and all kinds of **** to make that piss ant run. 12.90 is all it would muster. Car has been sitting about a year. To hell with it, ya know? So in the meantime, we've had this blown up 6.1 on a stand doing nothing. We fixed what needed fixing, and now we have a 1000 dollar 6.1 going in. We'll be using the Cascar intake and headers. We'll probably just put the 750DP on for now, may need bigger? We'll see.
